New and in-service grease testing

The history of lubricating greases dates back to ancient times. As early as 1400 BC, attempts were made to reduce axle friction in chariots. Analyses from axel hubs indicate that fat and lime were used to make a complex lubricant.1 Yet, the current state of lubricating greases only has less


Selecting the Right Grease for Pumping Systems

Pumps are critical in moving fluids, slurries or gases (compressors) in industrial plants, municipal water and wastewater systems and chemical processes. The compressed or pumped fluids move from high pressure to low pressure with the energy assist provided by the mechanical action of the pump. Whether the pump is a


How the NLGI HPM specification facilitates grease selection

The basic property needed for a lubricating grease is to separate the moving surfaces. This reduces friction and energy consumption, prevents wear from occurring, and gives components excellent durability. All greases should offer this basic protection provided they have the correct base oil viscosity. Other necessary properties are oxidation resistance,


Multipurpose Does Not Mean All-purpose

The term “consolidation” is very popular – especially when it comes to reducing the number of lubricants in an industrial facility. The thought is we can mitigate risks of accidentally using the wrong fluid by reducing the total number in storage. It’s also possible to enhance our purchasing power by


Castrol Launches First NLGI Certified HPM Grease in the Market

The National Lubricating Grease Institute (NLGI) announced the first product, Castrol’s Tribol GR SW 460-1, to be certified against NLGI’s new High-Performance Multiuse (HPM) Grease certification. In addition, NLGI certifies its enhanced performance in corrosion protection, high load-carrying capacity and low temperature. Read more

Grease Test Methods

Grease Test Method Write Ups for High-Performance Multiuse (HPM) grease specifications Note to reader: This document was prepared by Chuck Coe of Grease Technologies, LLC for the NLGI specification work being conducted in 2019 and 2020. Questions or comments can be sent to High-Performance Multiuse (HPM) Core Specification Cone


Factor Grease Into Asset Reliability

The role of grease, grease specification, rotating-asset reliability, and how the NLGI High Performance Multiuse grease certification program can help all stakeholders achieve their performance goals are the topics discussed in this podcast. Our subject-matter expert is Chad Chichester, an Application Engineer for Molykote Specialty Lubricants at DuPont. He provides


What’s different about grease?

Many myths and misconceptions exist about what grease is, what it’s used for and how it works. You’re no doubt familiar with oil lubricants like hydraulic oils, turbine oils, gear oils and so forth. They have one thing in common; they are composed of base oil(s) and performance additives. The


Certified Greases Advance Reliability

Managing lubrication is a primary component of your critical-asset reliability strategy. Unfortunately, ensuring that assets receive correct lubricants at proper intervals is often in conflict with the organization’s desire to simplify lubricant selection and reduce inventory. Lubricating many of today’s assets can be rather involved, resulting in complex lubricant needs
